An outlet aperture is disposed in fluid communication with the fluid flow path, and a ramp disposed within an internal surface of the shroud and engageable with the wedge.

Abstract: Adjustable nozzles for directing a solid-stream of fluid and associated methods for using the same are provided. According to one embodiment, the adjustable nozzle includes a base member having an aperture therethrough defining a nozzle inlet. The nozzle includes a plurality of elongate vanes each having first and second ends. The first ends of the vanes extend from the base member in a circumferential configuration so as to form an interior region. The second ends of the vanes are operable to define an expandable nozzle outlet. The nozzle includes a liner extending from the nozzle inlet to the nozzle outlet within the interior region. The liner is structured to direct the fluid from the nozzle inlet to the nozzle outlet. Each of the plurality of vanes is biased towards the liner to thereby support the liner and control the flow of the fluid therethrough.

Abstract: A flexible, self-adjusting flow nozzle is provided, optimally configured for agricultural uses. The nozzle flexes automatically in response to changes in fluid pressure, thereby maintaining an optimal droplet size and spray area for a variety of flow rates. The self-adjusting characteristic of the nozzle allows for the creation of a fully or semi-automatic spray system. The fully automatic system uses a GPS receiver to compare actual geographic data against a predetermined flow plan for automatically making adjustments to flow rate in order to accommodate both speed changes and varying crop needs. The semi-automatic system uses a manually controlled flow rate but utilizes the self-adjusting capabilities of the spray nozzle.

Abstract: The present invention is an apparatus and method to reduce unwanted spraying of fluids from hose nozzles. In the preferred embodiment of the invention, a hole filled cover is attached over an open end of the nozzle of the hose. When the hose is in a position where unwanted spray is unlikely to take place the spray stream passes through the cover unaltered. If the nozzle moves to a position where unwanted spray is likely to take place, the cover deflects over the liquid stream causing it to be disbursed or scattered rather than sprayed over a long distance. The invention finds particular application in the prevention of spraying of water from the high pressure cleaning nozzle in swimming pool cleaners onto nearby objects or persons.

Abstract: A fluid projection screen is formed by projecting a substantially spatially coherent stream of fluid, such as water, and directing it against a deflection plate. The deflection plate causes the stream to be broken up into fluid droplets which form a fan shaped screen extending at an angle to the fluid stream. A projector projects an image upon the screen, and visual acuity from edge to edge of the image is achieved by imparting a bend to the deflection plate which, in turn, imparts a bend to the screen so that the distances from the center and the edges of the screen to the projector are equalized.

Abstract: An adjustable arc sprinkler nozzle comprises a lower nozzle piece which is relatively rigid and an upper nozzle piece which is made of a relatively flexible, compressible material. A plurality of radial channels are provided in the upper nozzle piece for forming radial streams out of water flowing into the lower nozzle piece. A deflector ring having pairs of spaced deflecting fingers can selectively compress the upper nozzle piece by pushing down on it adjacent either side of each channel near the radially outer ends thereof. This pinches off the channel area and simultaneously bends the channels down over the lower nozzle piece to decrease the throw radius while keeping the precipitation rate relatively constant.

Abstract: A wax spray gun and spray nozzle for discharging an atomized stream of molten wax onto a vehicle body component or other substrate comprises a gun body having an atomizing chamber within which an internal wax spray nozzle and atomizing cap are located. A stream of atomizing air is tangentially directed into the atomizing chamber to form a rotating, swirling stream of atomizing air which is accelerated through a venturi inlet formed in the atomizing cap to impact and thoroughly atomize molten wax discharged from the internal spray nozzle. The atomized stream of molten wax is then discharged from the gun body into an external nozzle which preferably comprises a nozzle body having a wall formed with external threads which carry a coil spring. A flat is formed in the wall of the nozzle body with a discharge opening therein over which at least two spaced spring wires are positioned in the path of atomized molten wax emitted from the discharge opening.

Abstract: This invention permits a gardener to establish garden borders and to trim lawn edges simply with use of chemical herbicides thereby eliminating the need for edge trimmers or edge trimming spades. Thus, a hood accessory is provided for attachment to a hand held sprayer to conform spray from its spray head to a desired variable line width, Thus, for example, the sidewalk edge of a lawn need not be mechanically cut, but can be controlled by confining a herbicide flow pattern to a narrow line alongside the sidewalk. Similarly trimming the edges of flower or shrub gardens is feasible without the danger of killing the flowers or shrubs with herbicide. A low-price flexible walled plastic hood is thus fashioned for fitting onto the spray head. An adjustable mechanism then flexes the walls to produce a spray line width of the dimensions desired. All herbicide is thus prevented by the hood from being carried by the spray head or the wind into adjacent grass, shrubbery or flowers.

Abstract: An ultrasonic atomizing apparatus including an ultrasonic vibration generator and an ultrasonic vibrator horn having a cylindrical section connected at one end to the ultrasonic vibration generator and having a flared portion connected to the other end of the cylindrical section. The flared portion is flared and enlarged in diameter towards the tip end of the horn and is adapted to atomize liquid material on the flared portion as the liquid material is supplied from a liquid material supply nozzle to the flared portion. A hollow recess is formed in the flared portion opening toward the tip end of the horn. The geometry of the hollow recess is such that the cross-sectional area of the flared portion of the horn in any plane perpendicular to the longitudinal axis of the horn is the same as the cross-sectional area of the flared portion in all other planes perpendicular to the longitudinal axis of the horn.

Abstract: Apparatus for producing a spray of particles includes a shroud for restricting the spray produced by an atomizer, leaving a restricted arc or arcs over which particles can be ejected from the apparatus. The shroud includes at least one shielding element comprising an array of bristles. Each array of bristles can be carried by a flexible elongate element so that the form and extent of the array can be adjusted. The atomizer can be a rotary atomizer.

Abstract: A self-cleaning sprayer head having the capability to deliver a radially directed spray is disclosed. The sprayer head (10) includes a hollow, elongate casing (16), a flanged outlet end (28), and a plunger (42) mounted for sliding reciprocal movement within the casing. A spring (48) holds the plunger (42) in a retracted position. A flexible disc (38) connected to the outlet end of the casing defines an outlet gap (60). The disc (38) is connected to the plunger (42) for movement between a flush position, wherein the outlet gap (60) has a maximum width, and a spray position wherein the gap (60) has a minimum width. The disc (38) is configured to assume the flush position when the plunger (42) is retracted. When pressurized liquid is introduced into the casing (16), the plunger (42) moves in opposition to the spring (48) from its retracted position, through an intermediate position to a spray position. Simultaneously, the pressurized liquid passes through the ports (58) in the plunger and out through the gap.

Abstract: A sink rinsing device including an accelerating nozzle attached by a flexible stem to a fitting which fits onto a sink faucet above the aerator thereof. When not in use, the stem and nozzle lie flat against the underside of the faucet, out of the path of the water emerging from the faucet. When it is desired to rinse the sink, the stem is bent to bring the nozzle underneath the aerator of the faucet. The nozzle is removably fastenable to the fitting to secure the device in this position. Water emerging from the aerator of the faucet can now enter the inlet side of the nozzle, which directs a forceful stream of water against the sides of the sink. The fitting allows the nozzle to be rotated 360 degrees.
